To (0% whom it may concern:

Be it known that I, EPHRAIM H. B. KNOWL- TON, of Vatertown, inthe county of Codington, Dakota Territory, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specification.

This invention pertains to improvements in car-couplings, having for its object to effect the ready coupling of the cars and uncoupling of the same; and it consists of the combinations of the parts including their construction, substantially as hereinafter more fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is perspective view of my improved car-coupling. Fig. 2 is a plan view of the same, and Figs. 3, 4, and 5 are detail views thereof.

In carrying out my invention I employ two draw-heads, A A, each of which is formed at one side with a lower extension or projection, i

a, and an upper extension or projection, a, and at its opposite side with similar extensions, a a which, although farther apart, derive no peculiarity thereby. These latter extensions or projections o a receive and retain in position the coupling-pin B, headed above the upper extension or projection,

which head has a segmentremoved therefrom,

as at b, the purpose of which will appear farther on. The projections or extensions a a are provided with aligning grooves c c at the front edge of one side of the head, while intermediately of the projections or extensions a a is provided a vertical rib or bead, d, at the front edge of the opposite side of the head.

C is the coupling-hook, of peculiar construction, which is disposed between the projections or extensions a a, and is fitted to have vertical movement upon the pivotal pin D inserted through apertures in the'said projections. The coupling-hook pivot or pin D has one side flattened or cut away, as at D, for a certain portion of its length, while one side of the aperture or eye (1' of the hook itself is flattened or conformed to the cross-section taken at any point through the cut-away or flattened portion of the pin, whereby the hook and its said pivotal pin are locked and enabled to move together, thus permitting the hook to have both a vertical and a horizontal movement, as will more fully appear hereinafter.

The hook is provided at its inner pivoted end with a lateral tapered arm, 6, arranged about at a right angle to the body of the hook, while extending slightly forward from said arm is a short projection or stud, e, facing the arm e. The arrangement of these parts is such that when the hook proper is in position for coupling the arm e will be in alignment with the grooves c c of the extensions or projections to a, so as to be struck by the rib or head d of the opposite draw- 5 head to effect the coupling operation, while the projection or stud 6 stands, after the latter operation, so as to be acted upon by a contrivance for uncoupling the cars, which will be described farther on.

The coupling-hook O is provided upon its under side with a stud, f, ranging in the direction of the length of the hook and resting in arecess, f, in the upper surface of the lower extension or projection, a, holding thereby the i hook in its coupled position. At one (the outer) side of the recess f the extension or projection to is provided with an elevation, g, g which slopes downward toward said recess, and is provided in its upper surface with a recess, 9, to receive the stud f of the coupling-hook 0 when the latter stands in an uncoupled position.

The pivot-pin D is provided at its upper headed end with an arm, d which rests at its outer free end upon one arm of a V-shaped support, 72, applied to the upper side of the draw-head.

E is the uncoupling contrivance or cranked rod disposed in the draw-head closely to the coupling-pin B, its lower end resting in the lower one of the projections or extensions a a while its upper end is passed through the upper one of said projections or extensions, as at b, and provided with an arm, E, resting upon the other arm of the support h above referred to.

The uncoupling contrivance or cranked rod E is, as above stated, adapted by contact with the stud e of the coupling-hook O to disengage the hook from the couplin -pin of the opposite draw-head, and thus effect the uncoupling ot the cars.

The draw-heads are the counterparts of each other, being, however, reversed side for side as relates to the disposition or arrangement of their adjunctive parts, and are each provided with the ordinary coupling link and pin, as shown.

In operation it will be seen that upon the rib or head (I of the draw-head A coming into contact with the arm 9 of the hook C of the draw-head A the hook will be thrown or brought into engagement with the pin B of the drmv-head A, effecting the coupling operation and disposing the arm 0' of said hook in a position to be readily acted upon by the uncoupling eontrivance of the draw-head A when the uncoupling of the cars is to be effceted.

Having thus described my invention, what 5 I claim as new is- 1.. The car-coupling having its draw-head provided with a recess in its one side and with a vertical head or rib in its other side, and its coupling-hook provided with an arm standing in alignment with said recess, substantially as speci lied.

2. The car-coupling having its couplinghook provided at its inner pivoted end with an arm struck by the opposite draw-hea and which hook is also provided with a stud arranged adjacently to said arm and adapted to be acted upon by the uncoupling contrivance, substantially as set forth.

3. In a car-coupling, the draw-head having the pi vet-pi n and the couplin g-hook riding upward and laterally upon said pivot-pin and provided with a stud upon its under side and a stud at its inner end, one stud riding upon and resting in a recessed elevation of the drawat its one side a recess, and at one side of said recess an elevation, and the coupling-hook having at its inner pivoted end an arm aboutat a right angle to its body and a stud upon its under side, substantizitlly as set forth.

6. In a car-couplin g, the draw-head havin at its one side a recess, and at one side if said recess an elevation provided in its upper surface with a recess, and the coupling-hook locked to its pivot-pin and provided with a stud upon its under side and at its inner pivoted end with an arm about at a right angle to its body, and with a sin d facing said arm, substantially as specified.

7. In a car-coupling, the draw-head having at its one side a recess and at one side of said i recess an elevation provided in its upper sur- 1 u tace with a recess, and a coupling-hook provided at its inner pivoted end with an arm and a stud, and also upon its under side with a stud, said draw-head having at its opposite side a eoupling-pin and an uncoupling eontrivance or cranked rod, substantially as specified.
